The whale shark is the largest fish in the world.
This species can live a hundred years but reaches sexual maturity around 30 years. This is a problem for the protection of the species that has trouble reproducing fastly to counter mass fishing.
This shark feeds mainly on plankton, so it's easier to spot on a portion of the sea that is heavily loaded with plankton.
It is a species still little known, which moves a lot and can dive to almost 1.3 mile deep.
You can adopt one of them to help protecting the species, or report their position to a protection agency when you see it. We go through Sharks Institute ;).
Mammals have a horizontal tail.
Fishes have a vertical fin.
Some sharks can stay motionless on the sand (white tips reef sharks, nurse sharks, etc.).
These sharks don't have to swim to bring oxygen to their gills like other sharks (grey, hammerheads tc.)
The kakihona sushi (sushi wrapped in persimmon leaves) are really the best!
To eat them, you have to go to Nara!
